Abstract

Optical and IR interferometry will open new vistas for astronomy over the next decade. Space based interferometers, operating unfettered by the Earth's atmosphere, will offer the greatest scientific payoff. They also present the greatest technological challenge: laser metrology systems must perform with sub-nanometer precision; mechanical vibrations must be controlled to nanometers requiring orders of magnitude disturbance rejection; a multitude of actuators and sensors must operate flawlessly and in concert. The interferometry technology program at NASA's JPL is addressing these challenges with a development program that plans to establish technology readiness for the Space Interferometry Mission by early in the year 2001.
